air cleaner size?

[fe66comet]

I am trying to calculate the surface area needed for my air cleaner/ cleaners for my 445. I have a ceiling of 6500 and I have a max flow capacity of 1500 CFM. I doubt I will ever use that much but later I might supercharge. Thanks Guys

One of many on the 'Net:

Try Googling "air cleaner cfm" or "air cleaner size" or " air cleaner size calculator" and more should show up. K&N I think also has a number of calculators.

If this is anything like my 67 Lane setup. Flat Hood.
RPM intake and Holley. Drop base aircleaner and almost flat top equals 3 inch round KN type or paper.
I sometimes put the shiny new paper on for show time. I think it looks better than the working filter.
No room for a spacer.

Wow that's tight, I am going to make a custom dual quad drop base air cleaner to get more flow. It will have a flat top but with the dual quad it will be tight, may have to scoop it or drop the engine mounts. Either way I hate to any option as I like the hood lines as they are and the other would mean a lot of work. Was looking at the 68-69 cyclone scoop, guess I could live with it and it gives me 3 more inches.

Howie how much drop is your base?

[ScotiaFE]

I can measure it up for you and take a couple of pics.
I't may take a couple of days, my shift starts tonight and we have a snow storm coming. Fun WoW!

OK be careful out there it is supposed to be bad.

Here's that picture of the height of my Holley, RPM and 3" filter.

[fe66comet]

Yeah to the top, I think my intake may be taller? Can you measure from the lifter valley to you stick there? That would give me the big pic. BTW you must be beat after the snow it was a big one!

[fe66comet]

This is what I got.

Jon, ebock carbs? 

[fe66comet]

Yup I have had Holley, Rochester, Weber, Zenith and Carters. Just to name a few. The basic AFB has always been the most dependable and easiest to set up. Just my preference that's all.

Put a pair of Predators or Quadrajets on there and blow everyones mind.

I measured from the top of the air cleaner to the dist hole and have 11 1/2".
You should be able to squeeze another 1/2" on that.

Yup, getting pretty tired of the snow. It's been a snowy winter here.
